Introduction The aim of the study was to assess the frequency, features and management of dental emergencies at sea in France. Methods A descriptive study was carried out by retrospectively examining medical records of patients who were assisted by the French maritime TeleMedical Assistance Service (TMAS) from 2012 to 2016. Data were ranked in different categories: socio-demographic data, diagnosis, prescription, and monitoring or treatment prescribed. Results The TMAS recorded 9122 medical files for all medical emergencies. Among these medical records 135 concerned oral diseases. The main causes for dental emergencies are dental abscess (51.8%), tooth decay (33.3%), and dental fracture (8.9%). Even where teledentistry is validated for remote screening and oral lesion diagnosis, management of dental emergencies mostly requires a dental procedure. On board, without special equipment and/or specifically trained healthcare workers, this management often results in the prescription of medication. Discussion The International Medical Guide for Ships published by the World Health Organization could be updated to suit the latest recommendations of dental emergency management. This could facilitate the addition of a medical act to dental management, resulting in more effective treatment. Furthermore, simple and specific equipment could be added to the medical supplies.
